Or, just eliminate the subtitle and merge the one important word in the subtitle that isn't in the subtitle, and call it "The Open Source Data Science Master's Curriculum", which has the advantage that while it invokes the idea of a curriculum of the level of a Master's Degree, doesn't falsely present itself as an offering an actual degree, which it is not.

I don't think that's the intent, but I can see how it would give such an impression. That alone should be reason to change the title, though.
